There are a few reasons why graphite might be used as a lubricant instead of grease. One reason is that graphite can withstand higher temperatures than most greases, so it can be used in applications where the temperature is too high for grease. Another reason is that graphite has low friction, so it can be used to reduce wear and tear on moving parts. Finally, graphite is chemically inert, so it won't react with other materials it comes into contact with.
Graphite is the material used in pencils instead of lead. Graphite is a form of carbon that leaves marks on paper when it is used in a pencil. Contrary to popular belief, pencils do not contain lead.
Graphite does not undergo a chemical change when exposed to heat, so it does not "turn into" something else. Instead, it transitions directly from a solid to a gas through a process called sublimation.
Lead is not used in pencils. Instead, pencils contain graphite, which is a crystalline form of carbon that leaves a gray mark on paper when used. The term "lead pencil" is a misnomer that dates back to when graphite was mistaken for a form of lead.
First, the 'lead' in a pencil is not lead it is a mixture of graphite (a form of carbon) mixed with clay (the more clay the 'harder' the pencil). The lead portion is extruded in a long rod and then cut into lengths. The wooden sheath is made in two halves which are glued together round the lead.
Lead is. people often mistake the graphite in pencils for lead. Lead is used in batteries, in stained glass as the piece bonder, and in old paint. Lead is banned for use in paints, water pipe systems, and much more. Lead flashing is still allowed in building construction.
The predecessor of the graphite pencil was the lead pencil, which used a mixture of graphite and clay for the core instead of just graphite. Lead pencils were first developed in the 16th century.
No you cannot. Lead is not used in pencils, graphite is used instead. Graphite and clay is used and the proportion of graphite to clay is adjusted according to the hardness required.

No, it is not safe to use WD-40 on your bike chain as it is a degreaser and not a lubricant. It can strip away the existing lubricant on the chain and cause it to wear out faster. It is recommended to use a specific bike chain lubricant instead.

In some machines, using oil as a lubricant is not advisable due to the potential for oil to attract dust and debris, which can lead to increased wear and damage to components. Additionally, certain environments may expose machinery to high temperatures or chemical conditions that can degrade oil, resulting in reduced lubrication effectiveness. Instead, dry lubricants, such as graphite or PTFE, may be preferred for their ability to provide lubrication without the drawbacks associated with oil.

A pencil looks like an ink pen but uses pressure from a graphite core to write instead of ink. The graphite is dispensed onto the paper as you apply pressure, simulating the writing action of an ink pen.
While you can use a graphite pencil for your eyebrows in a pinch, it's not recommended. Graphite can irritate the skin and may not provide the desired color or finish. Instead, opt for products specifically designed for eyebrow application, such as eyebrow pencils or powders, which are formulated to be safe and effective for that area.
Graphite itself is pure carbon. But it might be possible for some samples of graphite to contain impurities of lead.
